Hollywood in 2011.1 One of the variables is the budget (in millions of dollars) to make the movie. Figure 1
shows two boxplots. One represents the budget data for one random sample of size n=30. The other
represents the values in a sampling distribution of 1000 means of budget data from samples of size 30.
See below for box plots

Explanation / Answer

The number of values included in the boxplot is equal to the sample size n = 30
The number of values included in the boxplot is equal to 1000 , as 1000 means are calculated and used as points , where each point is a mean of 30 points

The minimum and the maximum values of the boxplot are represented by the whiskers or the "lines" of the boxplot, however the dots represent the extreme low and extreme high
